SASH FOR DIALS.

Application led November 4, 1919.

To all whom t may concern:

Be :it known that I, CHARLEs H. HYDE, a citizen of the United States, residing at Winsted, Litchfield county, State of Connecticut, have invented a certain new and' useful Improvement in Sashes for Dials, of which the following is a full, clear, and exact description.

My invention relates to improvements in sashes for glasses for clock dials and the like, and has for its object to provide a sash in which the glass is easily removable and replaceable and also in which the holding means is adapted to be used in connection with glasses of different thicknesses. Heretofore one great trouble with sashes for clocks has been that in transportation the glasses were liable to be broken so that they had to be replaced. Heretofore these dials have been held in place by using a retaining ring, which was soldered in position. When this is the case, if a glass is broken only a skilled workman can put in a new glass and the result has been that it has been usually necessary to return the sash to the manufacturer. yIn some instances this is done by removing the hands of the clock and unscrewing the dial to which the sash is hinged and returning it to the factory. In other cases the clock as a whole is returned. In either case parts are liable to be damaged and furthermore there is considerable trou-` ble, expense and delay, which are obviated by the use of my invention.

Furthermore, the glasses, particularly the convex glasses, are liable to be of different thicknesses and if the glass manufacturer is called upon to deliver a glass of substantially uniform thickness the cost of obtaining such uniform glasses is greater than 1f he is allowed to send glasses of varying thicknesses. By the use of my invention glasses of different thicknesses can be secured in the sash without trouble with the result that there is a considerable saving in the cost ofthe glasses.

Where my invention is employed a small number of extra glasses can be sent to the retailer so that he will have them on hand and be able to make replacements if necessary, so that the di'liculty of broken glasses is practically eliminated and when the clock is once shipped neither it nor its sash is returned to the manufacturer on account of glass breakage.

Serial No. 835,722.

The principal feature of my invention is the retaining ring with its angularly disposed flanges and its wedge shaped cutaway portions and the projections on the frame Goan-ting therewith.

The following is a description of an embodiment of my invention, reference being had to the accompanying drawings, in which, i

Figure 1 shows a rear view of the sash embodying my invention;

Fig. 2 shows an enlarged portion of the sash of Fig. l;

Fig. 3 shows an inside elevation of a portion of the same;

Fig. 4 shows a section on the line Irl- 3, Fig. l;

Fig. 5 shows the rear view of a portion of a modification;

Fig. 6 shows an inside elevation of the same; and

Fig. 7 shows a section of the modified retaining ring on the line 7 7, Fig. 5.

Referring more particularly to the drawing, 1 is a dial to which is hinged a rimmed frame 2 for the glass. This fra-me 2 is provided with a flange 3 projecting inwardly from its rim and with three pins or projections L1 extending inwardly from the rim portion. 5 is a sheet metal ring having a auge 6 and a drawn-up rim portion 7 approximately at right angles to one another, the external surface at the point 8 of juncture being rounded. The portion 7, however, slants outwardly slightly so as to hug the rim of the frame and thus be adjacent to the bases of the pins 4:. In the drawn-up portion 7 at points -forresponding to the pins fl are three eut-away portions 9 having gradually rising wedge surfaces which are adapted to pass beneath the pins lVhere the ange 6 is of considerable width so that the ring will not readily yield radially, a notch 1() may be formed at the lowest point of one cut-away space as shown in the modified form of Figs. to 7, so that one of the pins may be passed through it. In assembling the parts the glass 11 is put in place and the ring is then put in position so as to Clamp it in place. In inserting the ring, the lowermost parts of two of the cut-away portions 9 are placed under two of the pins 4C and the ring is either snapped beneath the third pin, the frame and ring yielding sufficiently to permit lil this action and the rounded surface referred to facilitating it, orwhere the notch is used as in Figs. 5 to 7 the ring is pressed downward so that the third pin passes through the notch l0. lll hen the ring is seated beneath all pins fl it is turned Vso that the pins are engaged by the higher portions et the cut-away sur'liaces 9, thus .vedging the glass lirnily in place. the axial position oit the ring relatively to the pins depending uponthe thickness oi the glass. he glass is thus held Afirmly in place by the engagement ot the pins with the ring at three points, even though the glasses used are ot dil'lerent thicknesses. ly constructing the ring as described7 it can be niade oit sheet metal, stamped and drawn in an ordinary die press.

As will be seen, iny invention permits non-skilled workmen to readily replace a glass, and also permits the use ol' glasses of various thicknesses so that the stated objects of my invention are attained.

As will be evident to those skilled in the art, my invention perinits of various inedilications without departing 'troni the spirit thereof or the scope or the appended claims.

TWhat l claim is:

l. In a sash for clock dials and the like, the combination of an inwardly flanged outer sash trarne having` a plurality oi' inward projections carried by the riin thereof, a glass in said traine7 a holding ring within said trame and having a iiange adjacent to said glass and a peripheral portion approxi.- rnately at right angles to said flange, said peripheral portion having upon .its rear edge inclined surfaces adj acont to said projections and adapted to cooperate with said projections when said internal ring is turned so as to engage said projections and cianip said glass in said outer ring.-

2. ln sash for clock dials and the like, the combination ot an inwardly flanged outer sash 'frame having a plurality et inward projections carried by the rini thereof, a glass in said frame, a holding ring within said frame and having a lange adjacent to said and a peripheral portion having an outwarc ly slanting exterior surface approximately at right angles to said flange, said peripheral portion having upon its rear edge inclined surfaces ad jacent to said projections and adapted to cooperate with said projections when said internal ring is turned so to engage said projections and clamp said glass in said outer ring.

3. ln asash for clock dials and the like, the combination of an inwardly. flanged outer sash raine having a plurality oi'A inward projections carried by the rini thereof, a glass in said Yfrance, a holding ring within said trarne and having a flange adjacent to said glass and a peripheral portion approximately at right angles to said tlan're7 said peripheral portion having upon its rear edge inclined surfaces adjacent to said projections and adapted to cooperate with said projections when said internal ring is turned so as to engage said projections and clanip said glass in said outer ring, said flange of said ring being notched adjacent to the lower part ot one o'l said inclined portions.
